While I recognize it's an attempt to highlight the "takeaway", the submission title (currently "Choosing Monday for a surgery increases your chance of success 2 times") seriously distorts the actual study contents.
It's not analyzing "success" of the surgery, but "30-day mortality for (almost) any cause". (While death caused by the surgery is definitely failure, the absence of death isn't necessarilt "success".)
Also, there's no evaluation of "consciously choosing Monday" as a causal factor. There could be all sorts of pressures causing the surgeries on different days-of-the-week to have different risk factors, even if they're all "elective". (As they note: "One of the weaknesses of using administrative data is that we were unable to completely adjust for inherent selection biases that probably exist for elective procedures that are scheduled on weekends.".)
I can believe there's some effect of patient choice, possibly related to staff exhaustion, post-op complications happening during under-resourced weekends, but expect a lot of the effect found here to be due to factors pushing certain surgeries/deaths into certain days (and arbitrary categories that might have affected inclusion).
Submitted title was "Choosing Monday for a surgery increases your chance of success 2 times". That breaks the site guidelines, which say: "Please use the original title, unless it is misleading or linkbait; don't editorialize."
Cherry-picking the detail you think is most important from an article is a form of editorializing. If you want to say what you think is important about an article, please post it as a comment to the thread. Then your view will be on a level playing field with everyone else's.
